A $100,000 reward has been offered to help find the killer of long-time AC/DC manager Crispin Dye, who was bashed to death while on holiday in Sydney more than 20 years ago.

Dye, 41, from far North Queensland, was visiting friends and family in the inner city in December 1993 when he was assaulted and robbed of his wallet after drinking and socialising in Surry Hills.

A witness reported seeing three males of Pacific Islander appearance, aged in their late teens or early twenties, standing over Mr Dye’s unconscious body before they ran from the scene.

Police and ambulance paramedics were called to the scene and Mr Dye was rushed to St Vincent’s Hospital suffering major head injuries. He was later transferred to St George Hospital for specialist treatment but succumbed to his injuries and died on Saturday, December 25, 1993.

A number of investigations — and one coronial inquest (in 1995) — have been conducted in an attempt to find those responsible for Mr Dye’s death, however, as yet, no one has been charged.

Now, more than 20 years after his death, the NSW government has offered a $100,000 reward for information leading to the arrest and conviction of those responsible for Mr Dye’s death.

“By all accounts, Crispin Dye was a fun-loving, friendly and decent man, who was robbed of his life far too soon,” Detective Superintendent Mick Willing, from the NSW Police’s unsolved homicide team, said in a statement.

“There are people out there who know those responsible for Mr Dye’s death and we’re hoping this reward may prompt them to get in touch with police
